Restoration of Anterior Fractured Tooth

30 Sep 2014 - 8728

In recent years, the advancements in composite materials have made preservation of tooth structure a reality and thus changing the landscape of dentistry to becoming what it is today, more conservative and minimally invasive. Conservative and minimal invasion is always my philosophy of treatment, I believe MICD will become the trend in the future.

Total etching with phosphoric acid, enamel etching 30 seconds, dentin etching 15 seconds, the etching area is 0.5-1 mm beyond the bevel margin.

Then apply a universal adhesive in the enamel and dentin (Singlebond 2, 3M ESPE).

Tip and Tricks

1. Good communication with patient is the basic of a successful treatment

2. Shade selection is the first step to esthetic restoration. The time and light source is the key point during shade selection. Wax up helps a lot during the patient smile analysis and treatment planning.

3. Standard operation protocol. Pay attention in each step of the adhesive procedure.

4. Choose of right composite material, using composite multi-layering technique. Finishing and polishing will define the final result; remember to reproduce the natural anatomy and texture.

5. Periodical recall,  good OH situation help maintain the long-lasting result.
